I can\'t imagine why any producer might produce a library NOT tuned to 440, it would be completely useless. I think any orchestra that participates in sampling sessions can and will tune to 440, wherever they are based.
Well that\'s good to know, but my original question concerned the actual tuning of the instruments used for the sampling sessions. More libraries than many of you are aware of were originally sampled at A=443 (or even slightly higher!)then pitch-shifted down to A=440. This DOES cause a slight shift in timbre no matter how good a job is done. Most European musicians don\'t particularily like retuning their instruments to accomodate U.S. composers though some have learned to like it if they want to work!!
